J Nutr Biochem 2023; 116:109309. [PMID: 36871836 DOI: 10.1016/j.jnutbio.2023.109309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 01/13/2023] [Accepted: 02/24/2023] [Indexed: 03/07/2023]
Abstract
Fish oil or its major constituents, namely omega-3 poly-unsaturated fatty acid (n3-PUFA), are popular supplements to improve neurogenesis, neuroprotection, and overall brain functions. Our objective was to probe the implications of fat enriched diet with variable PUFAs supplements in ameliorating social stress (SS). We fed mice on either of the three diet types, namely the n-3 PUFA-enriched diet (ERD, n3:n6= 7:1), a balanced diet (BLD, n3:n6= 1:1) or a standard lab diet (STD, n3:n6= 1:6). With respect to the gross fat contents, the customized special diets, namely ERD and BLD were extreme diet, not reflecting the typical human dietary composition. Aggressor-exposed SS (Agg-E SS) model triggered behavioral deficiencies that lingered for 6 weeks (6w) post-stress in mice on STD. ERD and BLD elevated bodyweights but potentially helped in building the behavioral resilience to SS. STD adversely affected the gene networks of brain transcriptomics associated with the cell mortality, energy homeostasis and neurodevelopment disorder. Diverging from the ERD's influences on these networks, BLD showed potential long-term benefits in combatting Agg-E SS. The gene networks linked to cell mortality and energy homeostasis, and their subfamilies, such as cerebral disorder and obesity remained at the baseline level of Agg-E SS mice on BLD 6w post-stress. Moreover, neurodevelopment disorder network and its subfamilies like behavioral deficits remained inhibited in the cohort fed on BLD 6w post Agg-E SS.

Abstract
All nutrients are essential for brain development, but pre-clinical and clinical studies have revealed sensitive periods of brain development during which key nutrients are critical. An understanding of these nutrient-specific sensitive periods and the accompanying brain regions or processes that are developing can guide effective nutrition interventions as well as the choice of meaningful circuit-specific neurobehavioral tests to best determine outcome. For several nutrients including protein, iron, iodine, and choline, pre-clinical and clinical studies align to identify the same sensitive periods, while for other nutrients, such as long-chain polyunsaturated fatty acids, zinc, and vitamin D, pre-clinical models demonstrate benefit which is not consistently shown in clinical studies. This discordance of pre-clinical and clinical results is potentially due to key differences in the timing, dose, and/or duration of the nutritional intervention as well as the pre-existing nutritional status of the target population. In general, however, the optimal window of success for nutritional intervention to best support brain development is in late fetal and early postnatal life. Lack of essential nutrients during these times can lead to long-lasting dysfunction and significant loss of developmental potential.

Abstract
PURPOSE OF REVIEW Polyunsaturated fatty acids (PUFAs) are obtained from various sources, which can be incorporated in the routine diet to maintain the health. They provide protection from several diseases like osteoarthritis, cancer, and autoimmune disorders. Major focus is given to the PUFAs omega-3 (ω-3) and omega-6 (ω-6) fatty acids which are available in both terrestrial and in the marine environment. The main concern of this article is to review the key scientific reports in context with the human health consequences and advantages of the food sources of ω-3 and ω-6 fatty acids. RECENT FINDINGS ω-3 and ω-6 fatty acids are consumed by the population globally in the form of foods that are rich in fatty acids. Their nutritional effects have the capability to improve the physical functioning and metabolic rate of the body. These PUFAs contribute in various cellular activities like cell signaling, structural integrity and fluidity of cell membrane, the regulation of blood pressure, glucose level, the nervous system, inflammatory reactions, and hematic clotting. Animal and cell-based models represent that ω-3 and ω-6 PUFAs can regulate the skeletal muscle metabolism. The main concern of this article is to review the key scientific reports in context with the human health consequences and advantages of the food sources of ω-3 and ω-6 fatty acids.

Baseline red blood cell and breast milk DHA levels affect responses to standard dose of DHA in lactating women on a controlled feeding diet. Prostaglandins Leukot Essent Fatty Acids 2021; 166:102248. [PMID: 33516092 DOI: 10.1016/j.plefa.2021.102248] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 01/09/2021] [Accepted: 01/11/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND The importance of providing the newborn infant with docosahexaenoic acid (DHA) from breast milk is well established. However, women in the United States, on average, have breast milk DHA levels of 0.20%, which is below the worldwide average (and proposed target) of >0.32%. Additionally, the relationship between maternal red blood cell (RBC) and breast milk DHA levels may provide insight into the sufficiency of DHA recommendations during lactation. Whether the standard recommendation of at least 200 mg/day of supplemental DHA during lactation is sufficient for most women to achieve a desirable RBC and breast milk DHA status is unknown. METHODS Lactating women (n = 27) at about 5 weeks postpartum were enrolled in a 10-12 week controlled feeding study that included randomization to 480 or 930 mg choline/d (diet plus supplementation). As part of the intervention, all participants were required to consume a 200 mg/d of microalgal DHA. RBC and breast milk DHA levels were measured by capillary gas chromatography in an exploratory analysis. RESULTS Median RBC DHA was 5.0% (95% CI: 4.3, 5.5) at baseline and 5.1% (4.6, 5.4) after 10 weeks of supplementation (P = 0.6). DHA as a percent of breast milk fatty acids increased from 0.19% (0.18, 0.33) to 0.34% (0.27, 0.38) after supplementation (P<0.05). The proportion of women meeting the target RBC DHA level of >5% was unchanged (52% at baseline and week 10). The proportion of women achieving a breast milk DHA level of >0.32% approximately doubled from 30% to 56% (p = 0.06). Baseline RBC and breast milk DHA levels affected their responses to supplementation. Those with baseline RBC and breast milk DHA levels above the median (5% and 0.19%, respectively) experienced no change or a slight decrease in levels, while those below the median had a significant increase. Choline supplementation did not significantly influence final RBC or breast milk DHA levels. CONCLUSIONS On average, the standard prenatal DHA dose of 200 mg/d did not increase RBC DHA but did increase breastmilk DHA over 10 weeks in a cohort of lactating women in a controlled-feeding study. Baseline DHA levels in RBC and breast milk affected the response to DHA supplementation, with lower levels being associated with a greater increase and higher levels with no change or a slight decrease. Additional larger, dose-response DHA trials accounting for usual intakes and baseline DHA status are needed to determine how to best achieve target breast milk DHA levels and to identify additional modifiers of the variable breast milk DHA response to maternal DHA supplementation.

Abstract
CONTEXT Polyunsaturated fatty acids (PUFA) are important during pregnancy for fetal development and child health outcomes. The fatty acid desaturase (FADS) genes also influence PUFA status, with the FADS genes controlling how much product (eg, arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid) is metabolized from the precursor molecules linoleic acid and α-linolenic acid. OBJECTIVE The current review discusses the influence of FADS genotype on PUFA status of pregnant women, breast milk, and children, and also how FADS may influence child health outcomes. DATA SOURCES The Ovid Medline, Scopus, Embase, Cochrane Library, CINAHL Plus, PubMed and Web of Science databases were searched from their inception to September 2018. DATA EXTRACTION Eligible studies reported FADS genotype and blood concentrations of PUFA during pregnancy, in childhood, breast milk concentrations of PUFA or child health outcomes. DATA ANALYSIS In pregnant and lactating women, minor allele carriers have higher concentrations of linoleic acid and α-linolenic acid, and lower concentrations of arachidonic acid, in blood and breast milk, respectively. In children, FADS genotype influences PUFA status in the same manner and may impact child outcomes such as cognition and allergies; however, the direction of effects for the evidence to date is not consistent. CONCLUSION Further studies are needed to further investigate associations between FADS and outcomes, as well as the diet-gene interaction.

Plasma fatty acid patterns during pregnancy and child's growth, body composition, and cardiometabolic health: The Generation R Study. Clin Nutr 2017; 37:984-992. [PMID: 28456538 DOI: 10.1016/j.clnu.2017.04.006] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Revised: 01/27/2017] [Accepted: 04/07/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Exposure to different concentrations of fatty acids during fetal life may affect growth and metabolism. However, most studies examined individual fatty acids, whereas concentrations highly correlate and may interact with each other. We aimed to evaluate patterns of plasma fatty acids during pregnancy and their associations with growth, body composition, and cardiometabolic health of the 6-year-old offspring. METHODS This study was performed in 4830 mother-child pairs participating in a population-based cohort in the Netherlands. Around 20 weeks of gestation, we measured plasma phospholipid concentrations of 22 fatty acids, in which we identified three fatty acid patterns using principal component analysis: a 'high n-6 polyunsaturated fatty acid (PUFA)' pattern, a 'monounsaturated and saturated fatty acid (MUFA and SFA)' pattern, and a 'high n-3 PUFA' pattern. When the children were 6 years old, we measured their anthropometrics and detailed body composition (using dual-energy X-ray absorptiometry), and we calculated their body mass index (BMI), fat mass index (FMI), fat-free mass index (FFMI). At the same age, children's blood pressure, and serum insulin, HDL-cholesterol, and triacylglycerol were measured. RESULTS After adjustment for confounders and the other patterns, a higher score for the 'high n-6 PUFA' pattern during pregnancy was associated with a higher height, BMI, and FFMI in the offspring at 6 years, but not independently with cardiometabolic outcomes. The 'MUFA and SFA' pattern was not consistently associated with child body composition or cardiometabolic health. A higher score for the 'high n-3 PUFA' pattern was associated with a lower FMI, higher FFMI, higher HDL-cholesterol, and lower triacylglycerol. CONCLUSIONS Our results suggest that plasma fatty acid patterns during pregnancy may affect offspring's body composition and cardiometabolic health. Specifically, a pattern characterized by high n-3 PUFA levels was associated with a more favorable body composition and blood lipid profile.

Abstract
The epigenetic landscape is vulnerable to diets. Here, we investigated the influence of different polyunsaturated fatty acids (PUFA) dietary supplements on rodents' nervous system development and functions and potential consequences to neurodegenerative disorders. Our previous nutrigenomics study showed significant impact of high n-3 PUFA-enriched diet (ERD) on synaptogenesis and various neuromodulators. The present study introduced a second equicaloric diet with n-6 PUFA balanced by n-3 PUFA (BLD). The typical lab diet with high n-6 PUFA was the baseline. Transcriptomic and epigenetic investigations, namely microRNA (miRNA) and DNA methylation assays, were carried out on the hemibrains of the C57BL/6j mice fed on any of these three diets from their neonatal age to midlife. Integrating the multiomics data, we focused on the genes encoding both hypermethylated CpG islands and suppressed transcripts. In addition, miRNA:mRNA pairs were screened to identify those overexpressed miRNAs that reduced transcriptional expressions. The majority of miRNAs overexpressed by BLD are associated with Alzheimer's and schizophrenia. BLD implicated long-term potentiation, memory, cognition and learning, primarily via hypermethylation of those genes that enrich the calcium-releasing neurotransmitters. ERD caused hypermethylation of those genes that enrich cytoskeletal development networks and promote the formation of neuronal precursors. We drew the present observations in light of our limited knowledge regarding the epigenetic influences on biofunctions. A more comprehensive study is essential to understand the broad influences of dietary supplements and to suggest optimal dietary solutions for neurological disorders.

Abstract
BACKGROUND Choline, docosahexaenoic acid (DHA), and arachidonic acid (ARA) are essential to fetal development, particularly of the brain. These components are actively enriched in the fetus. Deprivation from placental supply may therefore result in impaired accretion in preterm infants. OBJECTIVE To determine choline, choline metabolites, DHA, and ARA in human breast milk (BM) of preterm infants compared to BM of term born infants. DESIGN We collected expressed BM samples from 34 mothers (N = 353; postnatal day 6-85), who had delivered 35 preterm infants undergoing neonatal intensive care (postmenstrual age 30 weeks, range 25.4-32.0), and from mothers after term delivery (N = 9; postnatal day 6-118). Target metabolites were analyzed using tandem mass spectrometry and gas chromatography and reported as medians and 25th/75th percentiles. RESULTS In BM, choline was mainly present in the form of phosphocholine and glycerophosphocholine, followed by free choline, phosphatidylcholine, sphingomyelin, and lyso-phosphatidylcholine. In preterm infants' BM total choline ranged from 61 to 360 mg/L (median: 158 mg/L) and was decreased compared to term infants' BM (range 142-343 mg/L; median: 258 mg/L; p < 0.01). ARA and DHA comprised 0.81 (range: 0.46-1.60) and 0.43 (0.15-2.42) % of total preterm BM lipids, whereas term BM values were 0.68 (0.52-0.88) and 0.35 (0.18-0.75) %, respectively. Concentrations of all target parameters decreased after birth, and frequently 150 ml/kg/d BM did not meet the estimated fetal accretion rates. CONCLUSIONS Following preterm delivery, BM choline concentrations are lower, whereas ARA and DHA levels are comparable versus term delivery. Based on these findings we suggest a combined supplementation of preterm infants' BM with choline, ARA and DHA combined to improve the nutritional status of preterm infants. STUDY REGISTRATION This study was registered at www.clinicaltrials.gov. Identifier: NCT01773902.

Abstract
Docosahexaenoic acid (DHA) is the predominant omega-3 (n-3) polyunsaturated fatty acid (PUFA) found in the brain and can affect neurological function by modulating signal transduction pathways, neurotransmission, neurogenesis, myelination, membrane receptor function, synaptic plasticity, neuroinflammation, membrane integrity and membrane organization. DHA is rapidly accumulated in the brain during gestation and early infancy, and the availability of DHA via transfer from maternal stores impacts the degree of DHA incorporation into neural tissues. The consumption of DHA leads to many positive physiological and behavioral effects, including those on cognition. Advanced cognitive function is uniquely human, and the optimal development and aging of cognitive abilities has profound impacts on quality of life, productivity, and advancement of society in general. However, the modern diet typically lacks appreciable amounts of DHA. Therefore, in modern populations, maintaining optimal levels of DHA in the brain throughout the lifespan likely requires obtaining preformed DHA via dietary or supplemental sources. In this review, we examine the role of DHA in optimal cognition during development, adulthood, and aging with a focus on human evidence and putative mechanisms of action.

Omega-3 Polyunsaturated Fatty Acids: The Way Forward in Times of Mixed Evidence. BIOMED RESEARCH INTERNATIONAL 2015; 2015:143109. [PMID: 26301240 PMCID: PMC4537707 DOI: 10.1155/2015/143109] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Revised: 05/18/2015] [Accepted: 05/28/2015] [Indexed: 12/18/2022]
Abstract
Almost forty years ago, it was first hypothesized that an increased dietary intake of omega-3 polyunsaturated fatty acids (PUFA) from fish fat could exert protective effects against several pathologies. Decades of intense preclinical investigation have supported this hypothesis in a variety of model systems. Several clinical cardiovascular studies demonstrated the beneficial health effects of omega-3 PUFA, leading medical institutions worldwide to publish recommendations for their increased intake. However, particularly in recent years, contradictory results have been obtained in human studies focusing on cardiovascular disease and the clinical evidence in other diseases, particularly chronic inflammatory and neoplastic diseases, was never established to a degree that led to clear approval of treatment with omega-3 PUFA. Recent data not in line with the previous findings have sparked a debate on the health efficacy of omega-3 PUFA and the usefulness of increasing their intake for the prevention of a number of pathologies. In this review, we aim to examine the controversies on the possible use of these fatty acids as preventive/curative tools against the development of cardiovascular, metabolic, and inflammatory diseases, as well as several kinds of cancer.

Effects of polyunsaturated fatty acid intake and status during pregnancy, lactation, and early childhood on cardiometabolic health: A systematic review. Prog Lipid Res 2015; 59:67-87. [PMID: 26025302 DOI: 10.1016/j.plipres.2015.05.001] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2014] [Revised: 05/19/2015] [Accepted: 05/21/2015] [Indexed: 01/01/2023]
Abstract
The importance of polyunsaturated fatty acid (PUFA) intake in fetal life and infancy has been widely studied in relation to child cognitive and visual development, but whether early life PUFA exposure is related to cardiometabolic risk factors is unclear. The focus of this systematic review was to evaluate the effects of PUFA dietary intake and blood levels during pregnancy, lactation, or early childhood (⩽5 y) on obesity, blood pressure, blood lipids, and insulin sensitivity. We identified 4302 abstracts in the databases Embase, Medline and Cochrane Central (April 2014), of which 56 articles, reporting on 45 unique studies, met all selection criteria. Many of the included studies focused on obesity as an outcome (33 studies), whereas studies on insulin sensitivity were relatively scarce (6 studies). Overall, results for obesity, blood pressure, and blood lipids were inconsistent, with a few studies reporting effects in opposite directions and other studies that did not observe any effects of PUFAs on these outcomes. Four studies suggested beneficial effects of PUFAs on insulin sensitivity. We conclude that there is insufficient evidence to support a beneficial effect of PUFAs in fetal life or early childhood on obesity, blood pressure, or blood lipids. More research is needed to investigate the potential favorable effects of PUFAs on insulin sensitivity, and to examine the role of specific fatty acids in early life on later cardiometabolic health.
